Abstract
A return member for a balance wheel of a timepiece, replacing a spiral spring. This return member includes a rake provided with a toothed sector arranged to work together with a balance wheel pinion. The rake has an axis of rotation allowing it to move between two extreme positions, called working positions, separated by a rest position. The return member also has two springs arranged to press the rake towards its rest position. Each spring is made up of an elastic blade arranged to store energy, then to return it to the rake. Each elastic blade works alternately so that they never work simultaneously. The return member may be in an escapement, a clockwork movement or a timepiece comprising such a movement.
Claims15
A clockwork movement escapement, comprising:
- a balance wheel pivoting on an axis of rotation of the balance wheel;
- an escape wheel;
- a lever;
- and
- a return member of the balance wheel, wherein the balance wheel is integral with a balance wheel pinion, the return member of the balance wheel includes
- a rake provided with a toothed sector arranged to work together with the balance wheel pinion, the rake comprising an axis allowing its rotation between two extreme positions separated by a rest position,
- a return mechanism comprising two springs arranged to press the rake towards its rest position, the springs comprising elastic blades arranged to store energy and to return energy to the rake and
- only one of the elastic blades stores and returns energy at the same time.
A return member for a timepiece movement, comprising:
- an escapement provided with a balance wheel, with an escape wheel and with a lever, the return member includes
- a rake provided with a toothed sector arranged to work together with a balance wheel pinion, the rake having an axis allowing it to rotate between two extreme positions, called working positions, separated by a rest position;
- two springs arranged to press the rake towards its rest position, the springs comprising elastic blades arranged to store energy and to return energy to the rake, wherein
- only one of the elastic blades stores and returns energy at the same time.
A timepiece movement, comprising:
- an escapement provided with a balance wheel, an escape wheel, a lever and a return member for the balance wheel, wherein
